System.ServiceModel and its child namespaces (System.ServiceModel.Channels, System.ServiceModel.Description, System.ServiceModel.Dispatcher, System.ServiceModel.Security, and System.ServiceModel.Security.Tokens) contain the types necessary to build Windows Communication Foundation (WCF) service and client applications.

This topic displays the types in the System.ServiceModel namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps does not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.
